Answer:

D

Step-by-step explanation:

plug in (3,2) to see if it's a solution:

A) does -3(3) + 2 equal -7?    yes

B) since 'A' is a solution then 'B' cannot be the answer

C) since (3,2) is a solution then 'C' cannot be the answer

plug in (2,-1) to see if it's a solution:

plug in (2,-1) to see if it's a solution:

-3(2) - (-1) equal -7?   no, it equals -5

only (3,2) is a solution so the answer is D
